In this paper we propose a mobile agent based QoS management system to satisfy the five functional principles of QoS architecture, i.e., integration, separation, transparency, asynchronous resource management and performance. Mobile agent paradigm is a unique paradigm in contrast to traditional client/server paradigm in a problem inherently distributed and complex, such as QoS management. This ...

There is a need for agent oriented software engineering (AOSE) methodologies that support the conceptual modelling of mobile agent systems. In this paper, we present m-GAIA, our extension to the GAIA methodology for modelling mobile agent systems. m-GAIA incorporates explicit constructs to perform the analysis and design of multiagent systems which include mobile agents. We also present our exp...

There is a lot of discussion regarding mobile agents. Some people claim they hardly have any additional value over other methods, while other people think it is a revolutionary way of building systems. Either way, there are a lot of agent systems, built in different ways with different technologies. While agent systems usually were built using scripting languages, since Java became popular, Jav...

Mobile Agents are autonomous and proactive software entities which act on behalf on an owner and have the ability to migrate through a heterogeneous network of computer .A mobile agent can also decide when to migrate and which node to access. In the past few years, mobile agent (MA) paradigm has received a great deal of attention. While MAs have generated considerable excitement in the research...

The goal of mobile agent systems is to provide a distributed computing infrastructure supporting applications whose components can move between different execution environments. The design and implementation of mechanisms to relocate computations requires a careful assessment of security issues. If these issues are not addressed properly, mobile agent technology cannot be used to implement real...

Communication, a fundamental concept in computing, allows two pieces of software to interact and to exchange information. It is an important aspect of mobile agent systems because mobile agents generally need to coordinate their activities through some type of communication. Using mobile agent technologies provides potential benefits to distributed applications; however, an agent’s ability to m...

The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this paper, we present evaluation of the performance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We derive the FANTOMAS...

Autonomous mobile agents have been purported as a promising new alternative to traditional distributed computing approaches, bringing many advantageous features. Notwithstanding this, mobile agent technology has yet to see wide deployment in open networks like the Internet. The lack of interoperability between agent systems has impaired such progress. Moreover, fears of security breaches by mal...

Mobile Agent is a type of software system which acts “intelligently” on one’s behalf with the feature of autonomy, learning ability and most importantly mobility. Now mobile agents are gaining interest in the research community. In this article mobile agents will be addressed as tools for mobile computing. Mobile agents have been used in applications ranging from network management to informati...

Network management applications using mobile agents require secure techniques for the lifecycle of the mobile agent, from both mobile agent and host points of view. Based on the analysis of the security threats that may occur during the mobile agent based network management applications, this paper presents Mobile Agent Security Facility (MASF). MASF has several key features: 1) a secure mechan...
